Designed To ANSI C Standards

The FED C Compilers (WIZ-C Professional and AVIDICY)  are designed to ANSI C Standards. This means that we have chosen the vast majority of the ANSI Standard and designed the C Compiler to
 that standard. Those areas which are not compliant are shown below:

• Types - the compiler supports char,int, long, and float types (integers in signed and
  unsigned form). double type is not supported.
• The ... form for functions is supported - but only through assembler
• Old style "Kernigan & Ritchie" function definitions are not supported
• Only those ANSI library routines which are relevant to typical micro-controller applications are included
